Bring a bet you are about to place, at the price you are being offered. This shows what it has to hit to break even, how much of that is the book’s margin, and whether the same bet is cheaper somewhere else.
No model, no pick, no opinion on the game — every number here is arithmetic on the market’s own quotes, which is why it works on any sport rather than only the one we price.
Why there is no model number here
We price one market properly — MLB totals — and when that model is scored against the market’s midpoint rather than its ask, it comes out behind the market. Showing you our probability beside your price would imply we know better. On the evidence we have, we do not, and the calibration page shows the working.
The margin and the line shopping above need none of that. They are true whether or not anyone can predict a baseball game.
